Definitions

  • the invention relates to an electrical machine, in particular brushless synchronous machine according to claim 1; such an electrical machine is in particular for use as a motor vehicle servo drive, preferably for cooler fans and / or hydraulic pump drives, intended.
  • An electrical machine with the first partial feature of the claim 1 is known from DE 41 39 843 C1.
  • the retaining webs are for Achieve a sufficient isthmus as narrow as possible held; this requirement contradicts a high one mechanical strength, particularly in drives high speed and additional unbalance load required becomes.
  • a drive starting from a electrical machine of the type mentioned at for one Mass product of advantageous manufacturing technology a drive be created by a high proportion of useful flow distinguished and internal inference losses also at high mechanical strength thanks to stable retaining bridge connections between the radially outer pole teeth and the radially inner rotor shaft minimized.
  • the Leakage flux leak path between the pole roots of the pole teeth and the rotor shaft are significantly reduced; who are not alone in terms of a maximum isthmus but in terms of one optimal mechanical production and strength dimensionable remaining retaining webs take over through the advantageous Connection of the slat segments according to the invention first type to the slat segments lying axially in front or behind second type the mechanical fixation of the whole Rotor laminated core assembly including that of it additionally held magnets.
  • FIG. 1 shows the top view of a lamella plane L1 of a complete rotor laminated core one by magnets M1-M8 excited rotor of an electrical machine whose associated stator structure according to e.g. basically from the DE 41 39 843 C1 of the type mentioned above can.
  • the advantageously cuboid tangentially magnetized Permanent magnets M1-M8 are each tangential between spokes axially extending individual pole teeth P1-P8, the slat segments S1-S8 in axially consecutive shown in FIG 2.3 slat levels L1-L8 are layered.
  • the complete rotor laminated core with magnets M1-M8 is opposite the rotor shaft RW of the rotor aligned and fixed.
  • slat segments S1-S8 per slat level L1-L5 provided, of which alternate slat segments first Kind S2; S4; S6; S8 essentially the actual one
  • Useful flow guidance of the magnets M1-M8 certain surface contour correspond and slat segments of the second type S1; S3; S5; S7 - in a manner generally known from DE 41 39 843 C1 - additionally originating from the pole tooth root of the pole teeth and have retaining webs H1; H3; H5; H7 leading to the rotor shaft RW; the retaining webs open into a hub ring on the rotor shaft side NR, into which the rotor shaft RW can be inserted or pressed is.
  • the lamella segments of the first type S2; S4; S6; S8 or the Slat segments of the second type S1; S3; S5; S7 change - as if 1 can be seen - in the circumferential direction per slat plane and in the axial stratification of a pole tooth - as can be seen from FIG 2.3 - from each other, such that - in the axial direction of the layer seen - each a pole tooth of the first type S2; S4; S6; S8 on the face of an axially present and / or subsequent Pole tooth of the second type S1; S3; S5; S7 with retaining bridge fixation can be connected to the rotor shaft RW and thus into a fixed one Parcel bandage can also be integrated without its own footbridge fixation is.
  • the front connection of the slat segments of the first type S2; S4; S6; S8 without retaining web on the slat segments second Type S1; S3; S5; S7 with holding bridge takes place after a special advantageous embodiment by a known Close-to link; for this purpose, packet-link formations are used K, molded on the edge on punched holes LO are; the punched holes LO can advantageously be used as Packing aid for attaching the slat segments a threading pin or to the package by means of a plug and axially tightenable screws or the like serve.
  • At least the slat segments are per slat level second type with the molded-on retaining webs and, if necessary the hub ring as well as the packet-link formations Parts of a one-piece stamped and bent part; for further Simplification and at the same time minimization of punching waste are the first type of lamella segments without a retaining bridge in the same operation and between the slat segments of the second type, punched horizontally from a one-piece sheet or shaped.
  • the axially end-end segment segments first Type S2; S4; S6; S8 when manufacturing the complete rotor laminated core are - as from the top view of the rotor laminated core 4 and the axial sectional views according to 5,6 can be seen - at least in each axially end Slat level also the slat segments of the first type in deviation from the basic solution concept of the present invention in each case via a molded retaining web H2; H4; H6; H8 to the rotor shaft tethered.
  • FIG 7 for an arrangement according to FIG 1-3 and in 8 for an arrangement according to FIG 4-6 each again based on of a layered complete rotor laminated core in perspective illustration explained, for better Clarity of the magnets to be picked up by the rotor laminated core are omitted; in words, the invention can be like summarize as follows:
  • M1-M8 a brushless synchronous machine with excitation through rotor-side magnets (M1-M8), which are made up of lamella segments (S1-S8) layered, by radial holding bars (H1-H8) pole teeth that can be fixed in relation to the rotor shaft (RW) (P1-P8) are distributed like spokes to reduce one Leakage flow through the holding bars with a high mechanical Strength provided, only every second slat segment (S1; S3; S5; S7) via a holding bridge (H1; H3; H5; H7) to the To connect the rotor shaft (RW) and the other lamella segments (S2; S4; S6; S8) to be layered so that they are axial on the face of the lamella segments with retaining webs, preferably can be connected by means of a punched package link are.
